I am a small business owner who just opened a branch office. I have some networking experience but have never set up a VPN. In the main office I have 10 computers (Win XP) connected to a server running SBS 2003 r2. I eventually will have up to 10 computers at the branch office. Both offices have Comcast Business Internet with advertised speeds of 16 Mbps downloads/2Mbps Uploads, with the option to upgrade to 22/5. Through my research on EE I have learned that I want to set up a IPsec tunnel between the two sites. I have other specific questions that I have not been able to find an answer for:
1) Do I need another server at the branch office if the main office server will maintain the necessary databases?
2) I will be moving photographs and other image files between the two sites. Will I notice a significant performance decline? Would the upgrade to 22/5 be worth the extra monthly cost?
3) The wide variety of VPN routers mentioned on this site is dizzying. I am prepared to spend up to about $500 per router. Which would be the simplest to set up and maintain? It would be a great help if it had an easy to follow step by step setup wizard.
